Question about Compaq PC Desktops

1 Answer

I moved my computer and when i did, it would not come back on. Monitor works but something is wrong with the brain--light comes on, but I don't hear it running. when this first happened it asked about recovery and then I don't know3 exactly what happened. does it need reset or whatever? Also, as stated, I don't hear it "gearing up" ike it used to. It is only six months old.

Try to check if you plugged all the correct sockets into place. check if you also got the outlet correct. this may only happen if you got something moved specially the towercase. if all connections are ok, check inside your tower if the RAMs are correctly seated. those are your memory.

Tip

Basic Computer Troubleshooting


Nothing happens at all when I press the power button.
  1. Unplug the computer and wait 10 minutes for the power supply to reset. Try again
  2. Plug something else into the outlet/power strip to ensure it has power
  3. No lights and no sound - This is just the power supply, If you aren't comfortable replaceing it, take it to your computer store.
  4. Lights come on, but no sounds. - This is commonly the power supply has lost some of the voltages, and needs replaced
  5. Lights come on, hear hard drive sounds, but no monitor - This is commonly bad monitor or video card. Try another monitor, if that doens't work, try another video card.

NO DISPLAY on screen but processor fan is work


If it seems like the computer booted up all the way except the screen is blank.

If so try connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok and works, then the video card inside the computer is good, but the original monitor is bad. If the Borrowed monitor does not work, then the video card inside the computer is bad.

If it does not seem like the computer booted up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.

I have a averatec desktop and the monitor gives an error message " no signal" and it black. The power is on, but nothing


If the monitor says "no signal" then either you don't have it connected to your computer correctly or you computer video card is not working (or maybe your computer is not actually starting up).
You could test this by using another monitor. You can also look on the back of the computer and see if you have connected your video cable to the proper output plug.
If something is actually wrong with the computer, we'll have to do more checking.

My friend karen press the power button, thre is no power... there blinking lights on the back of the computer near the fan power ...


Do you hear the harddrive start up? When you push the power button (or switch on the back) do the lights go out? If you hear fan running and hard drive start up then the computer itself might be on but the monitor isn't. Check the power to the monitor, the connection between monitor and computer to make sure they are all on and connected.

If you don' t hear the fan running then you have other problems. Any blinking lights would indicate something is getting power. I'm assuming the computer was working before the power button was pushed... If the monitor is actually working, you could hook up another monitor to check too then you have other problems but need more info to know what that could be.

would need to know the answer to the above questions as well as if it was working before, what was done, what changed between it working and this problem. Also what age the machine etc.

Yellow power light on HP SR1420NX


For reasons yet to be determined, your computer is not talking to your monitor.

This could be the monitor cable came loose from the tower (this is our favorite, because it is such an easy repair), or something on the motherboard (that is, anything) that is not functioning and preventing your computer from starting.

Unplug the connecting cable, and plug it back in again, making sure that it is seated properly.

Do you hear any sounds besides the fans? You should be able to hear the faint clicking of a hard drive starting up also. If you hear this, the problem is not in the computer, but in the communication to the monitor.

Good luck

I got one of my buddies laptops trying to fix it for him. It is a toshiba p700. I'm thinking there is something wrong with the screen. I don't know much about computers but when you press the power button,...


one thing you might want to try first, is to connect an external monitor and see if you see things, if you do, most likely your screen will need to be replaced. Probably the back lighting bulbs are burnt out or the inverter is dead.

I'm having problems starting my desktop computer. After I push the power button, I hear the computer working but it doesn't fully com on. There's no display on the monitor and I continue to hear the...


When you say you hear the computer working and working do you mean that the fans are going and the lights are on?

i ask this because the fans and power lights can come on just from the power supply coming on when you push power but that doesn’t necessarily mean the cpu is functioning.

Do you hear a post system beep and the hard drive reading files also?

Or does it just sound like only the fans cam on ?

If you think that possibly only the fans are working then try this

Shut down the computer and unplug the power cable.
Check to make sure monitor cable is connected all the way
Open the case and check to see that the video card is inserted all the way into the board properly
Remove the memory (RAM) and then put it back in to make sure it is properly seated in the slots
Plug in computer and try it again and if it still does not work then try clearing CMOS
on some systems you can clear the CMOS very easily by just holding down the insert key on your keyboard while pressing power button and continue to hold it down when releasing power button until you see something on the screen but since this does not work on all computers you might have to do it manually by moving the CMOS jumper on the board
(the CMOS jumper on the motherboard is usually the one closest to the little battery that you see on the board. with the computer off move the jumper over one notch to the other pin for a second and then put it back where it was (there are usually only three pins so this is easy step)
You should now be able to boot but you will need to go into the CMOS setup and set the clock again and other settings

If you still have a blank screen then let me know and i will take you to the next diagnostic step...

Hope this info helps
